Nanoscale superconducting memory based on the kinetic inductance of asymmetric nanowire loops
Andrew Murphy, Dmitri Averin, Alexey Bezryadin
The demand for low-dissipation nanoscale memory devices is as strong as ever. As Moore's Law is staggering, and the demand for a low-power-consuming supercomputer is high, the goal…
Asymmetric nanowire SQUID: linear CPR, stochastic switching, and symmetries
Andrew Murphy, Alexey Bezryadin
We study nanodevices based on ultrathin superconducting nanowires connected in parallel to form nanowire SQUIDs. The function of the critical current versus magnetic field, $I_{C}(…
Quasi-1-Dimensional Superconductivity in Highly Disordered NbN Nanowires
K. Yu. Arutyunov, A. Ramos-Álvarez, A. V. Semenov +6
The topic of superconductivity in strongly disordered materials has attracted a significant attention. In particular vivid debates are related to the subject of intrinsic spatial i…
Dark counts initiated by macroscopic quantum tunneling in NbN superconducting photon detectors
A. Murphy, A. Semenov, A. Korneev +3
We perform measurements of the switching current distributions of three w = 120 nm wide, 4 nm thick NbN superconducting strips which are used for single-photon detectors. These str…
Universal features of counting statistics of thermal and quantum phase slips in superconducting nanocircuits
A. Murphy, P. Weinberg, T. Aref +4
We perform measurements of phase-slip-induced switching current events on different types of superconducting weak links and systematically study statistical properties of the switc…
